+# How to Change the Orientation of Column Header Text in WPF TreeGrid?
+
+This example illustrates how to change the orientation of column header text in [WPF TreeGrid](https://www.syncfusion.com/wpf-controls/treegrid) (SfTreeGrid).
+
+Orientation of the TreeGrid column header text can be changed by editing the control template of the [TreeGridHeaderCell](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.TreeGridHeaderCell.html) and applying **RotateTransform**.
